Question

The bond angle around the central atom is maximum for:

• A. $H_{2}O$
• B. $H_{2}Se$
• C. $H_{2}S$
• D. $H_{2}Te$

Answer 1

Answer: (A)

$H_{2}O$

In $H_{2}O$ the central oxygen atom is $s{p}^3$ hybridized with two bond pairs and two lone pairs and the bond angle is ${101.5}^{\circ }$. In other molecules the orbitals have more p-character and due to larger size of the central atom.
